Be it lin rm that I, EDWARD J. CONDLON, a citizen of the United States, residing at .Balm lard, in the county of King an State ci "Washington, have invented certain new sind useful mgrovenients in Submarine Drog- Buclrets, tion.

My invention relates to improvements in submarine drag buckets or scoops; and the primar," ob'ect thereof is to improve and simplij)T such evices.

A further object is to so construct the improvement that by altering the line of draft teeth provided et the forward of the bucket will be caused to assume a greater downwardly-inclined relation, and thereby vary the degree of penetration of sai-:l teeth into the Water-bed.

With the above and other objects in view the invention consists of the parte, arrangement, and combination of parts hereinafter described, and succinctly pointed out in the appended claims.

Ln the accompanying drawings, 1n which like numerals of reference indicate 'like parts throughout the several views, Figure 1 is a View in front elevation of the present 4invention, a bortion of the cover of the bucket bcing bronzen awa I'. 2 is a section taken on line 2 2 of Eig. l. Fig. 3 is o side view with parts removed. Fig. 4. i a section taken on line 4 e ci Fig. 2, and Fi 5 is a disgrammatical view illustrating t' invention 111 use.

In carrying' out my invention i provide a bucket or scoop of approximately sfnnicinmk lar cross-sectional contour, the saine having its body and end walls formed of sheet metal, and sold body, which is indicated by reference-numeral l, has arranged 'on its interior angle-bars 2, to which it is secured, as by rivets or the like. (See Fig. l.) These anglebars project beyond the/,forward edge of the bucket and are pointed to form teeth which will penetrate and loosen the earth, as will be more fully set forth in the following, and at their rear portions scid bars ar)l bent inwardly to a. point approximately central of thc length of the bucket and then u )Wax-(ily, and to these last-na ined portions a c evis 3 is pivotcd by bolt 4f. This clevis is formed with a number of perorations 5, through which bolt 6 is adapted to project 'in order to var the line of draft, and thereby cause the toet i 7 to penetrate the earth to different depths,

or which the following is a specir'lc.- I

Reference-numeral f. indicates the cover, .the seme being /pivoted on a bolt 9 and having .forward edge cutout so cs 'the 3' when in lowered position. To l* cover elevated, and thcrcbj.r allow other materials loosened enter the bucket, l provide a cateo ch pivotcd on bolteend has hoehe: ond odepted to passthrongh opening il in the kcover and cet-ch ontlie inner face thereof, as illustrated bydotted lines in Fig. 2.

In operetion ecable l2 or the lillze is connected to the oler/"is 3, which cable can be op- 1 ereted in any' desired marmer, and another line is `reierably Tassed over a pulley, es 13, securec to an anc; or embedded in the bed of the stream or other Water and connected to e flexible connection 14, secured to the bottom of the bucket. By this "construction the bucket is held firmly to its work.

The catch 10 that the cover bucket is filled.

A spring, as 16, prerents'sccidentai din placement of the catch and serves to return the same to its normal position efter each releasement thereof. .o

l While I have herein shown a 'construction I which simple and ef'ricieint'in operation, I l

can be released when the reserve the right to make such alterations and changes the details of construction es fell within the scope of the appended claims. .Ho ving thus described my invention, wlmt l claim as new, and desire to secure by liettcrs Patent of tlk United States ol America, 1sl l. A drag-bucket having teeth projecting I beyond its forward, edge, an adjustable clevis connected to the bucket et the rear )ortich tl'ierccl', and nieces for holding said clovis as adjusted.

A drag-bucket comprising a body portion approximately semicircular in cross-sew tion, reinforcing-bers secured to the inner face thereof and having their forward ends proiccting beyond the adjacent edge of the buclrot, and ineens to which the draft-line is connected, said means being arranged at a l point op lesite the teeth.

3. A drag-bucket cornprisin, o body por tion, o. cover for closing seid orly portion, and ineens for holding seid cover in opened position.
